For this shot of Danielle Winkler at San Buenaventura State Beach in Ventura, I set a Canon 320 EX on the ground pointing upward at her, then triggered it with a Canon 60D using the 15-85mm EF-S zoom set to 31mm. The built-in flash trigger on the 60D is very handy when you're traveling light, but still want to experiment with lighting.
I mounted a polarizer over the lens to maintain the tone in the sky. Exposure was 1/250th at f/5.6. The photo was processed in Aperture 3 with the Silver Efex Pro 2 plug-in. The image grain was added during processing. The original picture was captured at ISO 160 and is virtually noise free.
I had a blast during the entire shoot experimenting with different lighting configurations. Don't underestimate the results you can get with a single flash, a great setting, and a talented subject.
